7 Claims. (Cl. 536) This invention relates to baking pan sets gening a bottom l0, having side walls 12 and end walls erally, and more particularly to sets for vbaking 13 extending upwardly from bottom thereof. At cake slabs, and the like, wherein it is desirable to their upper edges the side Walls 12 and end walls prevent the formation of a crust on the sides and 13 terminate in flanges 14. While the drawing f' '5I edges of the cake baked therein. illustrates aunitary assembly of three baking pans 6o It is an object of this invention to provide a P bound or secured together in aligned and spaced plurality of spaced baking pans in rigid assembly relation, it will be apparent that a greater or less having heat insulating material disposed adjoinnumber of pans may be included in the set if ing the pan Walls and between the contiguous walls desired. 10i of adjoining pans, conforming to and substan- A wire 11 encircles all of the pans P of the set 65 tially filling the space between such pans, and so as shown in Fig. 1 and is secured to the exposed attached to the pan walls as to eliminate the use walls 'l2-13 of the pansP by the flanges 14, which of rivets or similar fastening means piercing the are bent to embrace the Wire 11 and terminate adjacent pan Walls. f adjoining the adjacent pan wall, below the wire i With the above and other objects in View, as 1l.

I 18 in position, it is surrounded by a sheath S, hav- Reference being had more particularly to the ing a bottom 17, coplanar with the bottoms 10 of drawing, P represents a baking Ypan constructed the pans P, and side walls 19 extending upwardly iin accordance with the present invention, includtherefrom, resting ush against the adjacentvpan 110 together by a strap 25, which encircles the en- A extending in one continuous strip along and walls 12, and terminating slightly below the flanges 14. End walls 20 are provided on this sheath and extend upwardly in a position coplanar with the end walls 13 of the'pans P, to terminate in a flange 21 which is bent about the wire 11, in the same manner as the flanges 14 of the corresponding end walls 13 of the pans P. Thus the sheath Sconsisting of the elements 17, 19 and 20 encloses all of the remaining exposed portions of the insulating material 18, and is firmly retained in its position between the adjoining side walls 12 by the connection with the wire 11 embracing the entire pan set.

The insulating material 1S in the space between two adjoining pans P is consequently held in place by the sheath S and is housed betweenthe bottom 17, side wall 19 and end walls 20 of the sheath S and the coacting Vabutting connected flanges 14. It is therefore manifest that the spaces between the adjoining pans of the set are completely occupied by the insulating material 18 and the sheath cooperating therewith. It is further evident that this constructionjprovides a strong connection between the insulating material and the pans P without the use of rivets Vor similar fastening devices which ordinarily pierce the pan walls.

Stripsx21 of heat insulating material, are also.V provided for the corresponding and coplanar end walls 13 and outer side walls 12 ofthe pans P. To that end a continuous strip of heat insulating material 2l is placed along the alined end walls 130i the pans P. v A metallic covering Vir24 is applied to this insulating strip 21 which completely covers all expcsedsurfaces of the material, and

-Y is bent inwardly as at 22, to be clamped and engagedbetweenthe material 21 and the outer surface of the adjoining pan wall 13. The insulating strip 21, together with its covering 24, are secured to the walls 13 of the pans P by means of rivets 25 which pass through thevcovering 24, the insulating strip 2l, and the pan walls Y13. A separate heat insulating lstrip 21 together with its covering 24, is also applied to the outer side walls 12 of the end pans of the set.

All of the pans P of the pan set, are secured tire pan set and is also secured to the outer side walls 12 and aligned end walls 13 of the pans P and to the heat insulating member 21 by means of rivets 26 which pass through the strap 25, the covering 24, the insulating member 21 and the adjoining pan wall'. In this manner a pan set is obtained wherein the union of the pans is strengthened not only by the wire 11, but by the insulating member 21 and its covering 24 throughout the exposed sides of the pan set which assists the strap 25 in preventing lateral movement or distortion ofthe units of the pan set.

By the present structure it is manifest that all exposed pan walls are provided with coacting insulating members, rigidly and iixedly mounted in intimate contact therewith; that spaces and crevices are reduced to a minimum; that the in-` sulating material is fully covered and protected,

and that the pans P are secured together into ar means engaging therst said meansV for securing said iiller in position. i
